T-Shirt Yarn Rug Knitting Pattern – Easy Free Chunky Knit Rug Pattern
There is something deeply satisfying about making something beautiful for your home out of materials that already exist in your life. A t-shirt yarn rug sits right at that intersection of practical and creative — it uses recycled fabric, it works up quickly, and the finished product is thick, cushiony, and durable enough to last for years. Whether you are completely new to knitting or you have been at it for decades, this type of project is genuinely approachable. The yarn is chunky, the needles are big, and the results are impressive in very little time.
This post walks you through everything you need to know to knit your own t-shirt yarn rug from scratch. You will find a full free pattern, tips for choosing and making your yarn, guidance on needle size and gauge, and plenty of ideas for customizing the finished rug to suit your space. By the time you reach the end, you will have all the information you need to cast on and get started today.
What Is T-Shirt Yarn?
T-shirt yarn, also known as tarn (a combination of “t-shirt” and “yarn”), is exactly what it sounds like. It is yarn made from knitted jersey fabric — the same stretchy material used in most cotton t-shirts. When you cut jersey fabric in a continuous strip and then stretch it slightly, the edges roll inward and the strip becomes a rounded, rope-like strand that behaves remarkably like commercial yarn.
You can buy ready-made t-shirt yarn from craft stores and online retailers, and it comes in a huge range of colors. But you can also make your own from old t-shirts, bedsheets, or jersey fabric off the bolt, which is a wonderful way to use up textiles that might otherwise end up in a landfill. Either way, the resulting material is thick, soft, and extremely strong — which makes it ideal for floor projects like rugs.
T-shirt yarn typically falls into the super bulky or jumbo weight category, and it has a natural elasticity that regular wool or acrylic yarn does not have. This elasticity means your knitting will behave a bit differently than you might expect if you are used to working with standard yarn, but it also means your finished rug will have a little bit of spring underfoot.
Why Knit a Rug Instead of Crochet One?
Most t-shirt yarn rug tutorials online are crochet patterns, and while crochet produces beautiful rugs, there are real reasons to knit one instead. Knitting creates a fabric that is slightly more flexible and drapey, which means a knitted rug tends to lie a little flatter without as much curling at the edges — a common issue with crocheted rounds. Knitting with large needles on thick yarn also goes surprisingly fast once you get into a rhythm.
If you already know how to knit, there is no learning curve here. You are simply scaling up a skill you already have. And if you are a beginner, a rug like this one is a genuinely great first project. You only need to know how to cast on, knit, and bind off. That is it. No purling, no shaping, no tricky stitch patterns required — just satisfying rows of garter stitch that build up quickly into something tangible and useful.
Supplies You Will Need
Before you dive into the pattern, gather everything on this list.
Yarn: You will need approximately 200–250 yards of super bulky or jumbo weight t-shirt yarn for a small accent rug measuring roughly 18 by 24 inches. For a larger rug (approximately 24 by 36 inches), plan on 400–500 yards. If you are making your own yarn from old t-shirts, you can expect one large adult t-shirt to yield about 50–75 yards of tarn, depending on how wide you cut your strips.
Needles: For t-shirt yarn in the super bulky range (weight 6), use US size 17 (12mm) or US size 19 (15mm) straight or circular needles. If your yarn is on the thicker end (weight 7 or jumbo), go up to US size 35 (19mm) or even larger. Circular needles are helpful because they can hold more stitches, but straight needles work perfectly well for a narrower rug.
Scissors: A sharp pair is essential, especially if you are cutting your own tarn.
Tapestry needle: You will need this to weave in your ends at the finish.
Non-slip rug pad (optional): Recommended for any rug placed on a hard floor surface.
How to Make Your Own T-Shirt Yarn
If you want to use recycled materials, making your own tarn is simple. You will need cotton or jersey knit t-shirts — avoid shirts with side seams if possible, as tubular construction makes longer strips. Here is how to do it.
Lay your t-shirt flat on a cutting surface and cut off the bottom hem. Then cut horizontal strips across the body of the shirt, each about one inch wide. Stop about an inch before you reach the side seam on each side, so the strips remain connected. When you get to the top, cut the last strip all the way through.
Now spread the connected strips open so you can see the “ladder” of connected strips with the uncut sections at either side seam. Fold the shirt so that the left seam area is just inside the right seam area and vice versa, offset by one strip width. Then cut diagonally from one strip to the next through the connected sections. This creates one continuous spiral strip rather than a series of separate loops.
Stretch each strip along its length as you go. The edges will curl inward and the strip will become a rounded, rope-like strand. Wind it into a ball as you cut and stretch. You can adjust the strip width depending on how thick you want your final yarn — one inch is a good starting point for a chunky rug.
Understanding Gauge and Sizing
Gauge matters less for a rug than it does for a fitted garment, but it is still worth doing a quick swatch so you can predict your finished dimensions. In general, t-shirt yarn at a super bulky weight knitted on US 17 needles will give you approximately 2 to 2.5 stitches per inch in garter stitch.
The pattern below is written for a small accent rug measuring approximately 18 by 24 inches. This is a great size for in front of a kitchen sink, at a bedside, or in an entryway. If you want a larger rug, simply cast on more stitches and work more rows. Each additional stitch adds roughly half an inch to the width, and each two-row repeat adds roughly half an inch to the length.
Free Chunky Knit T-Shirt Yarn Rug Pattern
Finished Size: Approximately 18 inches wide by 24 inches long
Yarn: Super bulky (weight 6) t-shirt yarn, approximately 200–250 yards. One color or multiple colors.
Needles: US size 17 (12mm) straight or circular needles
Gauge: Approximately 2 stitches per inch and 3 rows per inch in garter stitch (this is approximate — exact gauge is not critical for a rug)
Stitch: Garter stitch throughout (knit every row)
Abbreviations:
CO = cast on
K = knit
BO = bind off
Instructions
Cast On: Using the long-tail cast on method or your preferred cast on, CO 36 stitches. If you are working with very thick yarn and large needles, the long-tail cast on creates a nice stretchy, even edge.
Row 1 and all subsequent rows: K across all stitches (knit every stitch in every row).
Continue knitting every row until your piece measures approximately 24 inches from the cast on edge, or until you have reached your desired length.
Bind Off: BO all stitches loosely. If you tend to bind off tightly, consider going up one needle size for the bind off row to keep the edge flexible and even.
Finishing: Cut your yarn, leaving a tail of about 6 inches. Thread the tail onto a tapestry needle and weave it in along the edge of the rug, going back and forth through a few stitches to secure it. Do the same with the cast on tail. Give the rug a gentle tug in all directions to even out the stitches, then lay it flat.
That is the entire pattern. There is nothing complicated about it, and that is the point. The beauty of this project is in its simplicity and in the gorgeous texture the yarn creates all on its own.
Variations and Customization Ideas
One of the best things about this pattern is how easy it is to personalize. Here are several ways to make your rug uniquely yours.
Stripes: The simplest variation is adding color stripes. Because you are knitting flat in garter stitch, changing colors is as easy as switching to a new ball of yarn at the beginning of any row. You can do bold, wide stripes by working ten or more rows in each color, or narrow stripes by switching every two rows. Try a combination of neutrals with one bright accent color for a modern look, or go full rainbow with a different color every few rows.
Color blocking: Rather than stripes that run along the length of the rug, you can work a large color block by working the first third of your rows in one color, the middle third in a second color, and the final third in your first color again. This creates a simple, graphic design that looks intentional and polished.
Texture with garter ridges: Garter stitch already creates a ridged texture, but you can emphasize this by using two slightly different yarn weights or textures held together. Try combining a thin jersey strip with a thicker one to create subtle tonal variation within each row.
Oval or circular rugs: This rectangular pattern is the easiest starting point, but once you are comfortable with the yarn and needles, you can explore oval rug patterns that start with a small number of stitches and increase at each end of every row. Circular rugs worked in the round on circular needles are another option. Both shapes involve a bit more math and technique, but t-shirt yarn is very forgiving and easy to rip back and redo if needed.
Braided border: After you finish knitting, you can add a braided border by cutting strips of contrasting jersey fabric and braiding them together, then hand-stitching the braid around the perimeter. This takes a bit of extra time but creates a beautiful finished edge.
Tips for Knitting with T-Shirt Yarn
Working with this kind of yarn is a bit different from working with conventional fiber, and a few simple tips will help your project go smoothly.
Keep your tension relaxed. T-shirt yarn has stretch, which means it is easy to pull your stitches too tightly without realizing it. Aim for a tension that feels looser than you might typically use. Your stitches should slide easily along the needle and the fabric should feel squishy rather than stiff.
Work on a flat, firm surface when possible. Big needles and bulky yarn can feel awkward in the air, but if you rest the needle tips on a table or your lap, the work becomes much easier to manage.
When joining a new ball of yarn mid-row, leave at least a six-inch tail on both the old and new ends. T-shirt yarn does not felt or stick to itself the way wool does, so you need those extra tails to weave in securely. Knot them loosely together at the join, then untie and weave in each tail separately when you finish.
If you are making your own tarn and your strips are uneven in width, do not worry about it too much. The variation in thickness actually adds to the handmade character of the finished rug. You can smooth out significant bumps by cutting the strip slightly narrower at the thick spots, but a little variation is completely fine.
Caring for Your Knitted T-Shirt Yarn Rug
One of the great advantages of t-shirt yarn is that it is almost always machine washable, since it is made from cotton jersey. Check the care instructions on any commercial yarn you use. For rugs made from old t-shirts, you can typically wash them in cold or warm water on a gentle cycle.
Lay your rug flat to dry rather than putting it in the dryer. High heat can cause cotton to shrink and the rug may lose its shape. If it comes out of the wash looking a bit rumpled, simply smooth it flat by hand while it is still damp and let it air dry. It will settle back into shape beautifully.
Over time, a knitted rug will compress slightly from foot traffic, which is normal. If it starts to look a little flat, you can fluff it up by lightly misting it with water and letting it air dry away from foot traffic for a day.
Where to Use a T-Shirt Yarn Rug
The finished rug is versatile enough to work in almost any room in your home. In the kitchen, a long narrow version in front of the sink makes standing more comfortable and adds a pop of color to a neutral space. In a bedroom, a soft rug beside the bed is the first thing your feet touch in the morning — and knowing you made it yourself makes that even better. In an entryway, a thicker, more durable rug holds up to daily foot traffic while welcoming guests with a handmade touch.
For a child’s room, try bright rainbow stripes or bold primary colors. For a bathroom, a smaller version in white or soft blue works beautifully. For a living room, consider working with neutral colors in a larger format to create a statement piece that grounds the whole room.
Sharing Your Finished Rug
Once you finish your rug and get it laid in place, take a photo and share it. The handmade community online is warm, enthusiastic, and full of people who will genuinely appreciate what you have made. Instagram and Pinterest are great places to share fiber arts projects, and there are wonderful knitting communities on Ravelry where you can even log this pattern and share your notes on what yarn you used and what you would do differently next time.
If you tweak the pattern — different stitch counts, different needle size, a color sequence you love — make note of it. Rug patterns especially benefit from your own personal notes because every yarn behaves slightly differently and what works perfectly in one yarn might need adjustment in another.
Final Thoughts
